The $60,000 buy, split between broadcast and cable television, seeks to contrast Byrne with President Barack Obama by citing government spending on "robotic squirrels," "money for a circus foundation," and a "futuristic food menu from Mars."

"Obama's wasted billions of dollars on boondoggles," Byrne says in the spot that will run through the Sept. 24 GOP primary, according to his campaign.

Byrne is running against several other Republicans to replace GOP Rep. Jo Bonner, who resigned in August to take a job with the University of Alabama system. Byrne, who started airing television ads on Aug. 29, raised the most cash out of the five competitive candidates in the GOP primary field.
